So, I'm bored right now so let's figure out how many times you'll need to do the event eb in order to get enough Psion to enchant the drone ring.
From what I've seen so far if you drop a swarm you get a chance for 25 Psion, along with that everyone gets a 100% drop for 5 Psion.
A drone ring costs 550 Psion to get to Lvl 10. Let's say you get really lucky and get 25 Psion for every swarm you drop and you drop said swarm every eb. 550 / 25 = 22 times you need to do the eb.
Not too bad but let's be serious, no one is gonna get 22 straight drops for this now are they?
So let's figure out the other way, you don't get a single 25 Psion drop no matter how hard you try. 550 / 5 = 110 times you need to do the eb. Now there's the unbelievable stat that we all know and hate from these promos.
So, you could be stuck doing this eb anywhere from 22 times, right up to 110 times, and that's only for a single ring, if you want two rings maxed or the best ring maxed then your gonna need to do this eb a lot more times.
That leaves me with a question, are you gonna be increasing the drops for this eb? Making the rings enchantable with aqua/inferno after the event or what? Cause that's a whole lot of times to do one eb.
